Help! Question about level 6 68 automag

I found and old 68 automagically in my dads garage. The manual says manufacture date is 1991. It's a level 6. I don't want it and would like to sell it but I don't have a clue what it would be worth if anything. Could anyone help please?

Yeah they would be hoppers. Most likely if that co2 tank is as old as that gun, it's pretty much useless. They need to be inspected and certified every couple years, and that usually costs more than a new tank, or close to it. I'd still stay at $80. I don't think you'd get more than that.
